When it comes to maintaining a safe and efficient water heater, the pressure relief valve is one small part that plays a massive role. As fall brings cooler, wetter weather to Seattle, it’s the perfect time to ensure this essential component is in top condition. Neglecting it could lead to severe water damage, system failure, or even safety hazards in your home.
In this guide, we’ll walk you through what a pressure relief valve does, why a seasonal check is important, and how Einstein Pros can help you keep your plumbing system in peak condition.
What Is a Pressure Relief Valve and Why Is It Important?
The pressure relief valve, sometimes called the T&P (temperature and pressure) valve, is a safety device installed on your water heater. Its job is to release excess pressure if your tank gets too hot or if water pressure builds up to dangerous levels.
If the valve fails to function, that excess pressure has nowhere to go—which could cause your water heater tank to rupture or even explode. That’s why routine inspections aren’t just good practice—they’re essential for safety.
Why Fall Is the Best Time for a Pressure Relief Valve Check
Seattle’s fall season brings cooler outdoor temperatures and increased demand for hot water. These changes can place extra strain on your water heater. Additionally, damp weather can lead to rust or corrosion around plumbing components.
By scheduling a check in October or early fall, you:
- Catch issues early before heavy holiday hot water usage begins.
- Prevent winter breakdowns when plumbers are in high demand.
- Ensure safety as your water heater works harder in cooler months.
For a complete seasonal inspection, many homeowners in Seattle combine a pressure relief valve check with other maintenance steps like water heater flushing and anode rod inspection.

How to Test Your Water Heater’s Pressure Relief Valve
While some homeowners choose to do a basic check themselves, remember that working with pressurized hot water can be dangerous. If you’re unsure, it’s best to have a professional from Einstein Pros perform the inspection.
Here’s the general process for testing the valve:
- Turn off the power supply – If electric, switch off the breaker; if gas, set the thermostat to “pilot.”
- Shut off the cold water supply to the water heater.
- Place a bucket under the discharge pipe connected to the valve.
- Lift the valve’s test lever to allow a small amount of water to escape.
- Release the lever – Water should stop flowing immediately.
- Check for leaks – If water continues to drip, the valve may be faulty and needs replacement.
Note: If the valve doesn’t open at all, it’s a sign it may be stuck and needs professional servicing.
Signs Your Pressure Relief Valve Needs Replacement
If you notice any of these warning signs, schedule a service call with Einstein Pros right away:
- Constant dripping from the discharge pipe.
- Rust or mineral buildup around the valve.
- No water release during a manual test.
- Excessively hot water coming from taps.
Neglecting these signs can lead to serious damage, including water heater tank failure.

The Risks of Ignoring Valve Maintenance
Many homeowners don’t think about their pressure relief valve until there’s a problem—but by then, it’s often too late. Common consequences of neglect include:
- Tank rupture from uncontrolled pressure build-up.
- Scalding hazards from overheating water.
- Flooding and water damage in your home.
- Costly repairs or full water heater replacement.
The small cost of a seasonal inspection can save you thousands in repairs and insurance claims.
